Elder guardians impose the mining fatigue effect on players without specifically targeting them. This behavior may be intentional, as it doesn't require direct eye contact. Relates to MC-269621, MC-269192, MC-264456, and MC-263315.

Steps to replicate

1. Paste the following command in an activated repeating command block:

   execute as @e[type=minecraft:elder_guardian] on target run say pending fatigue

2. Ensure that you remain out of sight of the elder guardian, as otherwise, it would target you.
3. Switch to survival mode and wait until you become affected by fatigue.

Observed behavior: The elder guardian applied the mining fatigue effect without targeting you, as evident by the absence of messages from the /say command.
Expected behavior: The elder guardian should target you when applying the mining fatigue effect, triggering messages from the say command accordingly.
